Device summary

Description

The STG4259 is a high-speed CMOS low voltage

dual analog SPDT (single pole dual throw) switch

or 2:1 multiplexer/ demultiplexer switch fabricated

in silicon gate C2MOS technology. It is designed

to operate from 1.65 V to 4.8 V, making this device

ideal for portable applications. It offers low ON

resistance (0.30

Ω) at VCC = 4.3 V. The SEL

inputs are provided to control the switches.

The switch S1 is ON (connected to common port

D) when the SEL input is held high and OFF (high

impedance state exists between the two ports)

when SEL is held low; the switch S2 is ON (it is

connected to common port D) when the SEL input

is held low and OFF (high impedance state exist

between the two ports) when SEL is held high.

Additional key features are fast switching speed,

break-before-make delay time and ultra low power

consumption. All inputs and outputs are equipped

with protection circuits against static discharge,

giving them ESD immunity and transient excess

voltage.
